The main purpose of this legislation, known as the "Payback Act," is to ensure that American consumers receive refunds for increased costs they incurred due to tariffs that were imposed without proper congressional approval. The act aims to address the financial burden these unauthorized tariffs placed on consumers, particularly working families, seniors, and small businesses. Key provisions of the Payback Act include the establishment of a refund formula that the Secretary of the Treasury must develop within 120 days of the act's enactment.
